A combination of Portal and Sokoban, AdaGate is a great example of OpenGL programming using the Ada language. It is F.O.S., of course.
While exploring a remote south-seas island you make a startling historical discovery. But before you can report your findings, an operational stargate transports you into a curious sequence of dungeons. Your escape will require the logical rearrangement of weird power cells, called Zero Point Modules (ZPMs), that can roll in only two directions.
You can shoot your portal guns at the dungeon walls to define a wormhole. But, in order to activate it, all of the ZPMs must be bumped into their sockets. Now, you can only PUSH the ZPMs. That means you will fail if you roll one into a corner or against a wall.
Escape each level and find your way back to a beautiful lake on the surface.
The degree of difficulty is now selectable. Each game resumes at the beach but progress from previous games is tracked. Complete all 4 levels to access the lake epilog and reset the game.
Uses fully modern OpenGL methods in Ada using textures, shaders and uniforms that achieves version 3.3 core profile contexts in a way that is sufficiently mainstream that it easily compiles and runs on both GNU/Linux and Mac OS-X systems. This project serves as a testbed for learning the complexities of modern OpenGL and GLSL.
Absolutely no coding efforts or compromises have been made to accomodate proprietary operating systems except for learning how to compile on OS-X. It relies on a thin SDL2 binding from Dan Vazquez, a thin OpenGL binding from "Lumen", a PNG reader by Stephen Sanguine, and SFML-Audio.
If one defines "modern" OpenGL to mean version 3.3 or beyond, then this may be the most functionally advanced demonstration of "modern" OpenGL using Ada to be found. The code itself is far from elegant, but serves as a working example, with focus on learning OpenGL. The Ada bindings used are thin, so the relationship to C++ methodology is quite transparent. Developers should note that these Ada bindings are usable as a standalone library for most any OpenGL project.
Media Files Note: The particular choices of sound, image, and shader files (*.fs) delivered are not essential to the function of the game and are easily replaced. This software is primarily intended as a tutorial example of modern OpenGL game assembly methods. The only requirements are that sounds be in WAV format, images be in PNG format, and shaders be updated to GLSL 330 specifications.

Allegro is multi-platform game programming library for C/C++ developers distributed freely, that provides many functions for graphics, sounds, player input (keyboard, mouse and joystick) and timers. It also provides fixed and floating point mathematical functions, 3d functions, file management functions, compressed datafile and a GUI. It can also be used for other types of multimedia programming.

Alpy provides a Python binding to the C Allegro game programming library. This binding is mostly focused with providing a basic "raw" interface to the library, trying to preserve most of the Python API similar to the C version to ease the transition to C programmers.

Whether you are a fan of science fiction, a space–science enthusiast, hobbyist, photographer, gamer or a patron of grass–roots libre arts and technology, you are sure to find the first successful images from the surface of Mars highly captivating. These mind blowing images were taken by NASA's Viking landers during the highly ambitious, billion–dollar mission first launched in 1975. However, many images were nearly lost to history due to magnetic tape deterioration and archaic proprietary technology.
With NASA's blessing, our team developed the technology to recover many of these images. This research tool was part of the design phase of our parent project, Avaneya — our upcoming libre cerebral science fiction game for the GNU operating system set on Mars, described in the words of Richard Stallman as an exciting, pioneering project.
Originally an internal research tool, overwhelming public interest compelled us to release the technology on this DVD for all. Now everyone can relive the original breathtaking experience that captured the world's attention and marked the first successful moment in history that humanity saw Mars — not as a distant, impersonal, celestial body, beheld through a telescope for centuries, but as a tangible and alien world well within its reach.

Castle Game Engine is a cross-platform 3D and 2D game engine for Object Pascal (FPC and Lazarus).
- It supports many formats for game assets, including X3D, VRML, Collada, Spine JSON, MD3 and others.
- Many graphic effects are possible, including bump mapping, shadows, shaders, mirrors, screen effects.
- Animation, collision detection, 3D sound and more features are available.
- An extensible system of 3D objects can be used, with out-of-the-box levels, items, intelligent creatures and more.
- The engine is portable -- for desktop, mobile, web plugin.
The engine is also used to develop view3dscene - a full-featured X3D / VRML browser and a viewer for many other 3D and 2D game formats.

ClanLib is a medium level development kit. At its lowest level, it provides a platform independent way of dealing with display, sound, input, networking, files, threading, etc. Beyond that ClanLib builds a generic game development framework, giving you easy handling of resources, network object replication, graphical user interfaces (GUI) with theme support, game scripting and more. It lets game developers avoid lowlevel trivials like setting up a directdraw window, sound mixing, reading image files, etc. All those things are simplified into object oriented classes and function calls. ClanLib uses a resource system to keep track of images, fonts, samples and music. It supports Targa, PCX, JPEG, PNG and BMP for images; wave files for sample; and Ogg Vorbis and MikMod for music. The resource system separates physical data formats from your code, and makes it easy to make themes and other plugins for your game. All classes in clanlib focus on making simple interfaces that are customizeable and expandable. This keeps your game code clean and simple, but still lets you to do advanced work. ClanLib is object oriented, which lets you operate at both high and low levels, minimizing redundant code but still letting you do things not supported by clanlib's high level APIs.

DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X...
DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games...
You can "re-live" the good old days with the help of DOSBox, it can run plenty of the old classics that don't run on your new computer!

Dolphin is an emulator for two recent Nintendo video game consoles: the GameCube and the Wii. It allows PC gamers to enjoy games for these two consoles in full HD (1080p) with several enhancements: compatibility with all PC controllers, turbo speed, networked multiplayer, and even more!
